LOG-TRUCK.

Specication of To all whom "it my concern:

4 Beit known that I, Gs'rAv KOMAREK, a citizen ofthe United States,residing at Louis,"'Missouri, have invented a certain new and usefulImprovement in LogfTrucks, of which the following is a full, clear, ande'xact description, such as will enableothers skilled Vin .the art. towhich it" appertains. to make and use the same.

This inventionrelates to log trucks such as are us'ed for transportinglong logs, one truck being arranged .adjacent'each end of the 'log.

The object of my invention is to provide 155s@ log 'truck of simpleconstruction which can be manufactured at a low cost. Figure l of thedrawings-is a top plan -view of a. log truck constructed' in accordanpewithA my invention; Fig. 2 is a side elevational view partly inv'verticalsection on the line 2 -2 of Fig. 1;- Fig. 3 is an elevationalview of the front end truck; Fig. 4 is a vertical transverse sectionalview'r talnan` yon the line 4-4 of Fig. l; and Fig. 2515 is a vertical'transverse sectional view taken on the line 5 -5 of Fig. 1.

Brieliy described, 'my improved log truck .consists of a cast metalframe provided with a bolster, sidev and end sills and draft beams,

tals on' the side sills for receiving the `journal boxes whichcoperatefwith the wheel axles vof the truck.

- Referring to thedrawings which` illustrate .the preferred form of myinvention, .A designates a bolster whose end portions are integrallyconnected to side sills B. The l.fronti and rear end sills vC. and D,respec- -%t^i'vely, of the truck are integrallyicnnected 40 to the sidesills B; and draft sills E, .which are' arranged between the bolster andthe front 'end-sill C, are integrally connected to said bolster and endsill, as shown clearly 'in Fi 1 and 2.- Pedestals F aresecured to theside sills BV for receiving the journal boxes which'coperate with thewheel axles. of the truck, as shown in broken'lines in Figs.' 1. and 3,and suitable tie-bars are connected to the lower ends of the pedestalsand to 'the' side sill on each side of the "truck, as shown in Fig. 2.Tlie bunk H, shown in broken lines '1n Fig. 4, on which tlie .ilegsrst,4is supported upon Vthe bolster ,l A offthe truck, and the side framesVB are Letters raten/s.

I-shaped in cross section, the vertical web 'of the bolster beingintegrally connected to -the vertical webs of the side sills, and thetop and bottom ianges of the bolster being integrally connected of` theside sills.

The draft beams E are providedwith integral lugs or abutments -1 whichcoperate with the follower plates of the draft rigging, not shown, and acarry-iron 2 is connected to said draft bea'ms for supporting thedraw-bar which passes through an integra-l with the draft beams, isAintegrally connected to the top flange ofthe bolster and to thetop'iange of the front-end sill: Gfso as to reinforce and strengthenthe' draft beams and tie them securely to the bolster range the draftbeams in a higher horizontal plane than the side sills, as shown in Fig.2,

beams are curved downwardly at the point where they are connected to thebolster and the intermediatev portion-of the front .end sill C isinclinedupwardly'so as to provide for this arrangement of the draftbeams.-

A log' truck of the character above-described, is exceptionally strongand .rigid frame .having draft beams formed integral with the bolsterand the front end sillof vthe truck both of -whichare integrallyconnected to the side sills of the truclgthe pedestal's" and tie-barsbeing the only" detachable or removable elements of the truck.

Having thus described 'my invention, what Jters Patent is:

1. A log' trunk-having 'a` 'cast metal frame which 'consists ofsidesills, end Lsills, a bolster, and draft beams all integrallyconnected together,iiand pedestals secured.;to the side s11ls.
